Specification of Letters Patent.

Application filed April 23, 1915. Serial No. 23,503.

T aZZ whom it may concern Be it known that I, \VlLLIAM W. VVILsoN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Pumps, of which the following is a specification.

This invention relates to pumps, and more particularly to pump operating means, and it has for its object to provide improvements in mechanism of this character which will be generally superior in point of relative simplicity and inexpensiveness of construction combined with positiveness and efficiency of operation, compactness in form, economy in power and freedom from frictional losses and wear and tear and which will be generally superior in efiiciency and serviceability. With the above and other objects in view, the invention consists 1n the provision, construction, formation, combination, association and interrelation of parts, members and features all as hereinafterdescribed, shown in the drawings and finally pointed out in claims. I

In the drawings:

Figure 1 is a side elevation of an improved pump mechanism embodying the invention, parts of the well-mouth structure being in vertical section upon the linea -a Fig. 2.

Fig. 2 is a front elevation of the same mechanism, similar parts being similarly sectioned vertically upon the line w m Fig. 1; and,

Fig. 3 is a transverse sectional viewtaken on the line 0c -m Fig. 1, and looking downwardly. Y

Corresponding parts in all'the figures are designated by the same reference characters.

Referring with particularity to the drawings, the improved pump mechanism 1s shown therein as provided for operating a pump rod A and a pump rod sleeve B which, in usual practice are oppositely reciprocated, the former within the latter, and

are respectively connected with the valved pistons (not shown) in the pump barrel. The particular organization or type, location and accommodation of the valved pump pistons is immaterial so far as the factors of the present invention are concerned, and it is understood that they with the pump barrel will be disposed at the proper point in the well so as to co-act in elevating the water or other fluid through the pump. The pump rod sleeve B is shown as playing through a casingbhead C at the mouth of the well, the same emg provided with a uitable watertight gland or stuffing box. To provide for direct actuation of the pump rod sleeve B I provide a pair of spaced actuating rods 1 and 5 which are connected with the upper end of the pump rod sleeve B by a cross head 6 through which the pump rod A reciprocates, such cross head being coupled onto the upper end of the pump rod sleeve B and provided with a suitable gland or stufiing box 7. The pump rod A is thus disposed intermediate of the two drive or connecting rods 4. and 5 which are ranged in a group each spaced from the others. Surrounding and rising above the mouth of the well is a suitable masonry or concrete base 8, upon which is disposed'the driving means D for the pump rod A and pump rod sleeve B; such driving means including three separate members or groups of working parts, (i, e and f which respectively actuate the drive rods 5 and 4, and the pump rod A. The drive means D comprises three cranks, 9, 10 and 11, one for each of the drive means members 03, e and f respectively, and three connecting rods, 12, 13 and 14' operatively coupling said cranks respectively with the drive rods 5 and 1 and the pump rod A respectively; said cranks being comprised within a unitary crank device 9 journaled at its ends, as at 15 and 16, in upright frame members 17 and 18 disposed upon the base 8; said frame members 17 and 18 having horizontal base portions 17 and 18 resting directly upon the base 8 and ranging rear wardly from the forward portion thereof. Rising from said base frame members 17 and 18 are vertical frame members 17? and 18 carrying journals fora drive shaft 19 Patented Nov. 11, 1919..

carryin at one end a drive wheel 20 adapt- I ed to be driven by through a suitable prime mover and carrying at the other end a pinion 21 meshing with a gear 22 fixed to the end of the unitary crank device 9. The base frame members 17 and 18 are likewise provided at their rearward extremities with upwardly and forwardly angled frame members 17 and 18 between which range a fixed shaft 23 from which depend three links 24*, 24 and 21; and separate alinement arms 25", 25 and 25 are pivotally connected each at its rearward end with a separate one of said links last mentioned, as at 26*, 26 and a belt or otherwise 26 respectively; said alinement arms being arranged in a transverse series, and respectively pivotally connected at their forward ends, as at 27, 27 and 27, with the drive rod 5, the pump rod A and the drive rod 4, at the point of pivotal connection of said drive rods and pump rod with the connecting rods 12, 14 and 18.

Alinement arm guide means E are provided for properly phasing the play of the alinement arms 25, 25 and 25, in the movement of said alinement arms responsive to play of the drive rods 1 and 5 and the pump rod A under crank and connecting rod actuation, which movement of which alinement arms is permitted or accommodated by the links 24*, 2% and 21; such alinement arm guide means so determining the consequent movement of the alinement arms that the points of connection of the respective alinement arms with the respective connecting rods and the respec tive drive rods and pump rod shall traverse rectilinear paths of movement, and the drive rods and pump rod be thus caused to traverse similar rectilinear or straight away paths of movement, avoiding wear and tear and frictional losses which would otherwise be present incident to untrue.

movement or distortion of the paths of movement from the rectilinear. These alinement arm guide means are disclosed in the drawings as comprising a fixed transverse shaft 28 ranging between the frame base members 17 and 18 and links 29 29 and 29 respectively, pivotally connected each at one end withsaid shaft 28 and at the other end with a separate one of the alinement arms. In order to accommodate the alinement arms in their operative play, each of the same is preferably formed into a central open frame portion 25 within which frame portions of each series of alinement arms, the shaft 28 is disposed. In order to provide for proper balance as among the working parts directly related to the pump rod A and the pump rod sleeve B, due to duplication of connections between the crank element G and the pump rod sleeve B, the pump rod A and its connecting rod 14, and its alinement arm 25*, the link 29*, and the incidental features and adjuncts of this mechanical grouping, are made of such total mass as to correspond in the aggregate to the total mass of material entering into the corresponding parts and features of the members 01 and e of the drive means D, the drive rods 5 and .k and the attendant corresponding features.

The operation, method of use and advan tages of the improvements in pumps or pump mechanism constituting the invention, will be readily understood from the foregoing description, taken in connection with the drawings and the following statement, all with respect to the embodiment of the invention herein disclosed.

Power is applied from the drive shaft 19 to the crank element or device 9 causing the connecting rods (l, e and to actuate the drive rods 5 and i and the pump rod A, the drive rods in turn in their reciprocation reciprocating the pump rod sleeve B; and the set of the various cranks 9, 10 and 11 is such that the cranks 9 and 10 are 180 spaced from the crank 11, whereby the pump rod A will complete the downward phase of its excursion as the pump rod sleeve B completes the upward phase of its excursion. All of this of course may be varied with the requirements of any particular service, so as to produce the desired or ciprocatory, or, in other words, to execute movements which depart somewhat from a straight away rectillnear nature. In order to prevent such departure, and to cause the pump rod and drive rods, together with the pump rod sleeve connecting with the drive rods, to execute true rectilinear movements, and thus avoid the otherwise present frictional loss, binding and wear and tear, the alinement arms 25*, 25 and 25 are provided, the same acting to cause true rectilinear movement of the driven parts. These alinement arms are phased by the alinement arm guide means E, as set forth, so that the pump rod and the pump rod sleeve are held to true rectilinear movement, the links 29, 29 and 29 definitely determining the play of the alinement arms as permitted by their suspension from the three links 24:, 24 and 24f. In other words, during either lift or fall of either one of the drive rods 5 and 4 or of the pump rod A, the respective alinement arm is permitted to execute only such compensatory movement as will permit true straight away or rectilinear movement of the pump rod and the drive rods and their connecting pump rod sleeve. Through the agency of. such alinement arms and alinement arm guide means having the function set forth, all of the disadvantageous operative aberrations customarily attending crank driven pump rod movement are elimiclosed in the drawings and herein described,

without departing from the spirit of the invention and a fair interpretation thereof.

Having thus disclosed my invention, I claim and desire to secure by Letters Patent:

1. In a pump, a pump rod or sleeve,

means for reciprocating the same, and

means for holding the pump rod to rectilinear movement in the reciprocation thereof; said latter means comprising an alinement arm, means constraining one end thereof to execute a definite path of move= ment, the other end thereof being pivotally connected with the pump rod, and guide means determining the path of movement of said alinement arm; and consisting of a link pivotally connected at one end witha stationary support and pivotally connected at the other end .with said' alinement arm; said alinement arm havin larged opening intermediate of 1ts ends, and a shaft being provided ranging through said opening and constituting the stationary support for one end of said link.

'2. A pump, comprising a 'pump rod, a pump rod sleeve within which the pump an enrod reciprocates', drive rods-connected with the pump rod sleeve, means for oppositely reciprocating the pump rod sleeve drive rods and the pump rod, three alinement arms each of which is provided at one end with means constraining said end thereof to execute a definite path of movement and each of which at the other end is pivotally connected with one of the said drive rods or said pump rod, each of said alinement arms being provided with an enlarged opening intermediate of its-ends, a shaft ranging through said alinement arm openings, and three links respectively connected with said alinement arms each at one end and with said shaft each at the other end.

Intestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM W. WILSON.
